Very useful info. I am biasing more towards the used hp/agilent/tek options. I see TLA715 is mentioned a lot in here as well in other threads. Any particular reason? Any other options that can be recommended? |

Some USB LA's have advanced triggering. I have the DigiView DV-518: https://tech-tools.com/trigger-cfg.html Don't know how it compares to the old boat anchors, but it sure is more capable than the usual Saleae toys. Anyway, if I had the space I would probably go with a boat anchor too. |

Some of the PicoScope models also have Advanced Triggers capabilities, including: Advanced edge trigger, Window trigger, Pulse width trigger, Interval trigger, Runt, Window pulse width trigger, Level dropout trigger, Window dropout trigger, Logic trigger, Digital trigger ... https://www.picotech.com/library/oscilloscopes/advanced-digital-triggers Ultra-deep memory - PicoScope 6000E Series oscilloscopes have waveform capture memories of up to 4 gigasamples. https://www.picotech.com/library/oscilloscopes/deep-memory-high-performance-oscilloscopes Regarding TEKTRONIX TLA715, the lowest price currently on eBay is US $699.99 + shipping from US $142.97 + import charges Est. $230.90, total US $1073.86. Doubtfully this amount can be called peanuts. |

Apart from that, and without knowing the tools * the picoscope advanced triggers mentioned would seem to be useful up to a point, but not for sequences of events * the digiview triggers seem useful * presumably separate filters are also needed for capturing the data If you can, use a tool's manual to understand how you can/can't use the tool's features for your expected use-cases. If you go for an old machine, verify that it is fully functional and that it has all the necessary probe hardware. Just as with scopes, the probes are "merely bits of wire" that are become separated from the "big important box" :( |
